"Should the vCard microformat property 'country-name' be in the language of the website?",
"I have following code on my website:\n\n<address class=\"vcard\">\n <span class=\"fn org\"></span><br>\n <span class=\"adr\"><br>\n <span class=\"street-address\"></span><br>\n <span class=\"locality\"></span>, <span class=\"region\"></span><br>\n <span class=\"postal-code\"></span><br>\n <span class=\"country-name\">Nederland</span><br>\n </span><br>\n</address>\n\n\nAs you can see the country-name contains Nederland which is Dutch for the Netherlands. Should this always be specified in the language of the website, for search engines to recognize? Or is this only readable in English?\n\nBecause it displays on the site it should be in the language of the website, but I am questioning whether or not this is effective to SEO."

"programming wrt cloud computing",
"I have been wondering over this question for a while. I have read up stuff about cloud computing(and there has been an unusual hype these days). I have understood the theory behind, how using a cloud can help me use my resources efficiently and blah blah blah. So my question is how to use(if we can) this technology in our programs? For example, with multi-core processors dominating the market, we know our programs should support multithreading(and probably should not crash when porting from single-threaded processor to multi-threaded one). So Is there any such programming paradigm we should be following or is the cloud concept completely aloof from our programs written in object-oriented and procedural languages??"

"Is merely requesting app transparency permissions sufficient for ensuring google mobile ads are iOS14 compliant?",
"We have an app that shows Google banner, interstitial and reward ads. In iOS14 there are new requirements for App Tracking. This impacts Google Mobile ads as described here: https://developers.google.com/admob/ios/ios14. We've implemented all their steps, including the final step:\nfunc requestIDFA() {\n ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in\n // Tracking authorization completed. Start loading ads here.\n loadAd()\n})\n\n}\nIs this sufficient for iOS14 app tracking compliance as far as Google mobile ads are concerned?\nThe reason I ask is that with the European personalized ad consent we had to also include in the GADRequest (see: https://developers.google.com/admob/ios/eu-consent#forward-consent):\nlet status = PACConsentInformation.sharedInstance.consentStatus\nlet extras = GADExtras()\n \nif status == .nonPersonalized || status == .unknown {\n extras.additionalParameters = ["npa": "1"]\n}\n\nDo we need to do something similar for iOS App Tracking?

When setting the CompositeTransform.CenterX/Y to the values of ManipulationDeltaRoutedEventArgs.Position, the usercontrol will rotate with center points that get more wrong for every gesture, and occasionally speed away. \n\nI'm using a CompositeTransform as the render transform of my user control, and I have hooked up to the ManipulationDelta-event like so:\n\nprivate void UserControl_ManipulationDelta(object sender, ManipulationDeltaRoutedEventArgs e)\n {\n //this.transform is my composite transform \n //which is set to be the render transform of the user control\n this.transform.CenterX = e.Position.X;\n this.transform.CenterY = e.Position.Y;\n this.transform.ScaleX *= e.Delta.Scale;\n this.transform.ScaleY *= e.Delta.Scale;\n this.transform.Rotation += e.Delta.Rotation;\n this.transform.TranslateX += e.Delta.Translation.X;\n this.transform.TranslateY += e.Delta.Translation.Y;\n }\n\n\nIt seems that e.Position doesn't give me what I want, and unfortunately the documentation is very brief, only stating Gets the point from which the manipulation originated.

"Compile-Time container of functors for controlling an algorithm?",
"Suppose i want something simple like the following:\n\nI have an core-algorithm, which randomly selects one of the specialized algorithms (specialized at compile-time) and process this algorithm. These specialized algorithms are implemented trough functors. \n\nThe question is now: how to implement a container, which is build at compile-time, where the core-algorithm can first check the size of this container (\"i got 4 algorithms -> need to randomly select algorithm 0-3\") and can then execute the functor in this container (\"randomly chosen 2 -> process the third functor in container\").\n\nHow would one implement it as simple as possible? I suppose it is possible.\n\nIs there any connection to the curiously recurring template idiom? (wiki link)\nIs there a simple way with the use of Boost::Fusion? (official doc)\n\nEdit: All the algorithms will be used in the core-algorithm. The use pattern (random-numbers) is a runtime-decision (so i don't need compile-time-rands). The algorithm just has to know the container of functors and the size of this container for safe access."

"React hot-loading stopped self updating",

Once I though I had a good enough knowledge from react I decided to try and integrate React with symfony and I was almost successful in that. I managed to get a symfony view to load react components but was unable to do live edits, and by that I mean, I have to restart webpack and press F5 to reload the page. So I decided to go back to the tutorials I made and see what I was doing wrong. When I start a new react project (by using \"create-react-app projectName\") to see where I failed, this project had the same problem, I had to reload the webpack so I could see the changes I made, and I know that this project was able to live-edits (because was the first tutorial I made and was working at the time), all I needed to do is to save the document and the page should automatically show the changes I made.\nI think that showing the code its not important in this case because it's a fresh project by using the command I said before, but anything you need I can try to explain you or giving the code."

"OSGi logging from legacy apps?",
"Let's say I have four legacy jars:\n\n\nmy-library.jar\nmy-app.jar\nmy-other-app.jar\nlog4j.jar\n\n\n\"My App\" and \"My Other App\" are unrelated applications, both with main() functions. They both use various library functions from \"my-library-app\". All three do logging through log4j (really slf4j, but I just want to keep the example simple).\n\nCurrently, the two applications are set up with two different log4j config files, which cause them to log to two different files.\n\nNow I want to convert everything to OSGi. So I bundle up the first three each as a separate bundle, convert the main() of the actual apps to Activators, and either bundle up or find an existing bundle of log4j. I start both apps in the same OSGi framework.\n\nBut now the two distinct apps no longer log to different files! Right? There's only one instance of log4j running in the JVM, and it gets its configuration out of one single log4j.properties file.\n\nSo maybe instead of bundling each of my four jars separately, I make three bundles:\n\n\nMy Library\nMy App plus log4j\nMy Other App plus log4j\n\n\nNow I can get different logging config files for the two different apps. But what about log calls from My Library? The My Library bundle will latch onto one of the two copies of log4j, and now all log messages produced from My Library will come out in one specific one of the two log files - let's say the one for My App. But that's true even if it's a log message from My Library due to a call from My Other App! They'll go to the wrong log file.\n\nSo maybe bundle:\n\n\nMy Library plus log4j\nMy App plus log4j\nMy Other App plus log4j\n\n\nNow the log messages from My Library are going to their own log file, which I guess is better than some of them going to the wrong app's log file, but still, it's not great. That file has log messages from both apps, and neither of the log files intended to be for either app have all log messages from those apps. \n\nSo maybe bundle:\n\n\nMy App plus My Library plus log4j\nMy Other App plus My Library plus log4j\n\n\nBut now what's the point of OSGi? I'm not sharing use of My Library or of log4j. And in reality it will likely be even worse - there will be a bunch of jars that I have to stick multiple copies of into all of my actual app bundles, simply because I want to see their log messages associated with the app that caused them.\n\nSo maybe back up and try something different: I don't think this is possible in log4j, but in (say) slf4j I could go back to the original bundle plan:\n\n\nMy Library\nMy App\nMy Other App\nlog4j\n\n\nAnd then I do something like put MDC information in each thread saying what app the thread is from. React to that MDC info to determine what log file it goes into.\n\nBut it seems like that won't work either! A call from some thread in My App to some function in My Library could cause a new thread to be spawned from My Library, which would not necessarily be associated with that MDC.\n\nAnd it's worse than that: My Library could have some thread that is shared by any app that uses My Library, so cannot possibly be associated with some such marker.\n\nSo, all in all, I'm stumped. Any suggestions would be greatly appreciated. Thanks in advance."

"Powershell winform event handlers in classes cause scope trouble",
"I'm experimenting with creating GUIs and using classes in powershell. I'm really new to both of those things (and to a lesser extent powershell generally) so bear with me.\nThe problem I am having is I cannot make any control which makes any modification to the form. This is because when adding a handler to a button it goes into the scope of the button class in the handler and none of the form references are accessible.\nMost examples of UI code in powershell are not class heavy. I realize that I could get around this, if it was not in a class, by having the handlers and form being in the global scope, but I'm trying to make use of classes so that I have the ability to make base forms and inherit from them. And I want to see what is possible.\nBelow is some test code including multiple of my attempts to make this work with the results commented. I even got the idea of passing the form reference into the handler (DI style). Things I'm trying are all over the map since I'm also feeling out basic powershell syntax.\nAdd-Type -AssemblyName System.Windows.Forms\nAdd-Type -AssemblyName System.Drawing\n\n \nclass Window : System.Windows.Forms.Form\n{\n Handler () {\n Write-Host Handler\n $this.BackColor = [System.Drawing.Color]::Blue\n }\n\n HandlerArgs ([object]$sender, [System.Eventargs]$eventArgs) {\n Write-Host HandlerArgs\n $this.BackColor = [System.Drawing.Color]::Blue\n }\n \n $HandlerVar = {\n Write-Host HandlerVar\n $this.BackColor = [System.Drawing.Color]::Blue\n }\n\n HandlerParam ($form) {\n Write-Host HandlerParam\n $form.BackColor = [System.Drawing.Color]::Blue\n }\n\n $HandlerVarParam = {\n (params $form)\n Write-Host HandlerVarParam\n $form.BackColor = [System.Drawing.Color]::Blue\n }\n \n Window ()\n {\n $button = New-Object System.Windows.Forms.Button\n $button.Text = "ClickMe"\n $button.AutoSize = $true\n $this.Controls.Add($button)\n\n\n\n # $button.Add_Click( $this.Handler )\n # "Cannot convert argument "value", with value: "void Handler()", for "add_Click"\n # to type "System.EventHandler": "Cannot convert the "void SelectNextPage()" \n # value of type "System.Management.Automation.PSMethod" to type "System.EventHandler"."\n\n # $button.Add_Click(([System.EventHandler]$x = $this.Handler ))\n # turns the window blue immediatly\n \n # $button.Add_Click( $this.HandlerArgs )\n # "Cannot convert the "void HandlerArgs(System.Object sender, System.EventArgs eventArgs)" \n # value of type "System.Management.Automation.PSMethod" to type "System.EventHandler".""\n\n # $button.Add_Click( $this.HandlerVar ) \n # this works but turns the button blue instead of the form\n\n # $button.Add_Click( { $this.Handler } )\n # does nothing?\n\n # $button.Add_Click( { $this.Handler() } )\n # Method invocation failed because [System.Windows.Forms.Button] does not contain a \n # method named 'Handler'.\n\n # $button.Add_Click( $this.HandlerParam($this) )\n # turns the window blue immediatly \n\n # $button.Add_Click( { $this.HandlerParam($this) } )\n # Method invocation failed because [System.Windows.Forms.Button] does not contain a\n # method named 'HandlerParam'.\n\n # $button.Add_Click( $this.HandlerVarParam $this )\n # parse error\n # I can't find a syntax that lets me pass a param to a function in a variable\n }\n}\n\n\n$foo = New-Object Window\n$foo.ShowDialog()\n\nAlthough it's likely super obvious already, c# is my main language.\nPerhaps this is just a limitation of the OO support in an interpreted scripting language, or maybe it's just my syntax deficiency. Is there any pattern that will get me what I want in this class-based structure? I would hope the pattern would be a general solution for doing normal form-things with handlers of form-controls."

"I'm trying out the beta/unreleased code for EMM 2.0 (which I believe is now MDM) and I undestand that the mobile app store and publisher function have been moved to Enterprise Store, however I'm unable to see/add mobile apps - I only see Gadgets and Sites.\n\nI was looking for the source in case I missed the plugin, but at https://github.com/wso2/carbon-store/tree/master/features/extensions I only see Gadgets and Sites.\n\nCan someone tell me how to enable mobile apps and/or point me to the mobile app plugin source?\n\nFYI, I installed ES from http://wso2.com/products/enterprise-store/ and also master branch from the following:\n\n\nhttps://github.com/wso2/product-mdm.git\nhttps://github.com/wso2/carbon-device-mgt-plugins.git\nhttps://github.com/wso2/carbon-device-mgt.git"
